* Add request pool to improve delivery performance Fix #7909 * Ensure connection is closed when exception interrupts execution * Remove Timeout#timeout from socket connection * Fix infinite retrial loop on HTTP::ConnectionError * Close sockets on failure, reduce idle time to 90 seconds * Add MAX_REQUEST_POOL_SIZE option to limit concurrent connections to the same server * Use a shared pool size, 512 by default, to stay below open file limit * Add some tests * Add more tests * Reduce MAX_IDLE_TIME from 90 to 30 seconds, reap every 30 seconds * Use a shared pool that returns preferred connection but re-purposes other ones when needed * Fix wrong connection being returned on subsequent calls within the same thread * Reduce mutex calls on flushes from 2 to 1 and add test for reaping
